Title: Television receiver
IPC: H04N5/44
Filed: 1964-11-12
Abstract: 1,068,879. Multiple radio signalling. BRITISH TELEMETER HOME VIEWING Ltd. Nov. 12, 1964 [Nov. 14, 1963], No. 46213/64. Heading H4L. A television receiver is provided with means for minimizing the effects of local oscillator errors in the tuner circuit. The I.F. output from the tuner 10 is supplied to a narrowband amplifier 16 passing a band of 40À5 to 42 mc/s. centred about the I.F. audio carrier of 41À25 mc/s., and to a broadband amplifier 12 having a pass band of 40 to 47 mc/s. passing all the signals from the tuner 10. The output of the amplifier 16 is supplied to a mixer 20 together with an output of 32À75 mc/s. from a crystal controlled local oscillator 22, the sum signal being supplied via a narrowband amplifier as a 74 mc/s. signal of constant-amplitude to a further mixer 26. The output of the broadband amplifier 12 is also supplied to the mixer 26 at an amplitude less than that of the output of amplifier 24, the difference signal in the range 27À5 to 33 mc/s. being supplied via an I.F. amplifier 30 to an A.M. video detector 32. The arrangement is such that any unwanted frequency drift appearing at the output of the tuner 10 due to inaccuracies in the local oscillator of the tuner 10 is balanced out by taking the difference frequency from the mixer 26 and results in a video carrier which is amplitude modulated with the video signal and frequency modulated with the audio signal and has the frequency precision of the oscillator 22, the audio carrier being unmodulated and having the frequency of the oscillator 22. The intercarrier difference frequency is derived at the detector 32 and supplied via I.F. amplifier 36 to the F.M. audio detector 38. The necessary modifications to the response characteristic of the I.F. amplifier 30 to avoid interference between sound and vision are discussed, Figs. 5 or 6 (not shown). In the second of these arrangements compensation of the video output of detector 32 also in necessary and a correcting circuit attenuating the lower video frequencies is described, Fig. 10 (not shown).

Title: Ventilation and/or air temperature control apparatus
IPC: F24F1/02
Filed: 1973-10-12
Abstract: 1490336 Air conditioning vehicles DELANAIR Ltd 10 Oct 1974 [12 Oct 1973] 47877/73 Heading F4V [Also in Division G3] An air-condition unit for a vehicle incorporates a multiplicity of valves for controlling both the proportions of hot and cold air in a given flow path and the distribution of such flows. In particular, the air supplied to lower levels in the vehicle is required to be warmer than that supplied to upper levels. The valves are flaps whose position is varied to provide selected temperature and/or ventilation conditions under the control of electric circuitry (see Division G3) responsive to the temperature. Fans (not shown) blow air into ducts 3a over a refrigerator-cooler 2 and also over a heater 4 which may be part of the engine-cooling water system. Flaps 6, 8, 10, 12, 14 and 20 control the delivery of different proportions of cooled and heated air to different destinations in the vehicle either automatically in dependence on electric sensing of internal and external temperature orin certain circumstances, with the automatic control wholly or partly overriden-manually, e.g. to effect defrosting by directing the maximum heating effect at the windscreen. In particular, the flaps 6, 8, 10 and 12 provide an adjustable flow path which (in the case where 6 and/or 12 is fully open and 8 and 10 fully closed) can completely bypass the heater. Flap 14 controls the flow of heated and/or cooled air to the upper part of the vehicle either directly (with the flap open) or via trunking 16 and vents 18 and 22. Vents 18 direct air on to the vehicle windscreen and this flow is controlled by further valves 20. Similar arrangements provide flow to lower level outlets 24, 24a. Appropriate conjoint action of the various flaps in response to the output of the control system circuitry is effected by causing the circuitry to determine the angular position of a shaft 54, Fig. 4 (not shown) fitted with cams which are mechanically connected to the flaps.

Title: Improvements in rotary actuators
Inventor: HUTCHINSON DESMOND ERNEST
IPC: H01H3/26
Filed: 1966-10-26
Abstract: 1,206,932. Valves. ENGLISH ELECTRIC CO. Ltd. 24 Oct., 1967 [26 Oct., 1966], No. 47962/66. Heading F2V. [Also in Division H1] An actuator is powered by a motor 2, 4 mounted on the actuator input shaft 6 which drives a double gear 14 mounted eccentrically on shaft 6 through ball-bearings 16. Gear 14 rolls around a normally stationary annular gear 18 and imparts a stepped-down drive to an output gear 20 since gears 18 and 20 have nearly the same number of teeth 22, 24. Gear 20 drives an output shaft 26, e.g. for driving a butterfly valve, secured thereto, through 90 degrees. Two position switches 50 are controlled by a follower rod 52 bearing in an eccentric groove 54 in gear 20 (Fig. 4). Rod 52 bears on a finger 62 of a plate 64 pivoted on a pin 66, and plate 64 carries adjustable set-screws 70 for operating switches 50 through arms 71. As rod 52 moves outwardly, plate 64 pivots anticlockwise and at one extreme position of gear 20 (i.e. after 90 degrees rotation) a first switch 50 is opened, and the second remains closed. When gear 20 rotates in the opposite direction, at the other extreme position the second switch 50 is opened, and the first is in a closed position. The switches are wired so that one is "normally open' and the other "normally closed" (extreme positions of gear 20 are shown in Fig. 4 by keys 58). Gear 18 is normally held stationary by a worm 28 engaging its outer teeth 30 (Fig. 3). Worm 28 can be driven by a handle 32 to drive shaft 26, shaft 6 remaining stationary. When the output torque of the actuator rises above a predetermined limit, worm 28 moves axially against a centering spring (76, Fig. 3) and one or the other of two torque-limiting switches 74 is opened, depending on the direction of rotation, to stop the motor. One switch 74 is "normally open" and the other is "normally closed". Axial movement of worm 28 pivots a plate 84 about pin 66, plate 84 having an integral lever 78 with a pin 80 received in a groove 82 in worm 28, and plate 84 carries two adjustable setscrews 86 which operate switches 74 through arms 71. Set-screws 86 may be removed from plate 84 and screwed into holes (88, Fig. 5) in plate 64 to provide four position switches. A further set-screw can be screwed into a hole (90) in plate 64 to operate a fifth position switch (92, Fig. 5). A visual indication of the position of output gear 20 is provided by a marked disc 34 and dial 36. Disc 34 is driven by a spindle 38 secured to a member 40 in gear 20. A further indication may be obtained through a finger 94 on plate 64 controlling a rod 96 coupled to a potentiometer.

Abstract: 1,263,700. Dosing apparatus. BELL'S ASBESTOS & ENG. Ltd. 17 Nov., 1969 [12 Oct., 1968], No. 48470/68. Heading B1C. [Also in Division F2] A hot and cold fluid mixing valve has spring- loaded ball valves 17, 20 disposed in the respective inlets 16, 19 and actuated by diametrically opposed surfaces (57), (58) on a cam 33 which is rotatable about but captive on a tube 31 fixed via a frusto-conical member 26 to a spring-loaded diaphragm 24. Cold fluid pressure is communicated below the diaphragm by a passage 22 while the pressure of the mixing chamber 32 acts on the top of the diaphragm so that if a valve on a spray nozzle, for example, is opened downstream of the outlet 37 the pressure drop in the mixing chamber causes the diaphragm and cam 33 to rise and open the valves 17, 20. A secondary liquid connected at 72 may be injected into the outlet via apertures 43 by the pumping action of fixed piston 70 in a chamber formed in the member 26 and movable with the diaphragm acting in conjunction with check valves 73, 74. An alternative outlet for liquid is at 75 which is normally closed by a plug 76. In a modification, Fig. 7 (not shown) the top of the cam is formed as a piston (108) movable in a cylinder (104) formed in a temperature control knob (105) which piston ejects a secondary liquid into one of two alternative outlets (114), (115) from an inlet (111) when the cam and piston move to actuate the valves. The outlets (114), (115) each communicate with one of two alternative outlets for the mixed fluid.
